Dear all,

I would like to transform a say 4272 x 3 matrix (this matrix
basically tells us the distance between each pairs of
observation) onto 1068 x 1068. 

In MATLAB, this can be transformed using the following
command: 

load GIS_4NN.txt;
W4NN = sparse(GIS_4NN(:,1), GIS_4NN(:,2), GIS_4NN(:,3));

Is there any equivalent command like the above in STATA?

Any tips on this much appreciated. 

Thanks,

Susan
